The Family Tree Learning Center has been shut down because of the allegations.

The mother asked WISN 12 News to protect her identity because she's concerned about the welfare of her child.

"(I am) mad. Very, very, very mad and scared, really scared," she said. "I've been told not to talk about it to anybody, and I'm upset that I'm not getting any answers."

Cedarburg police told WISN 12 News they are investigating at least two reports of young children being sexually abused by an adolescent at the day care, but more potential victims were identified after police met with parents over the weekend.

Late Tuesday afternoon, WISN 12 News learned of a closed hearing at the Ozaukee County Courthouse, where a juvenile was brought before a judge to face the allegations.

Because of juvenile court rules, WISN 12 News was not allowed to attend the hearing.

However, WISN 12 News learned police do not suspect any adults at the center of committing sexual assaults.

That was little comfort to the mother.

"You're supposed to trust your day care center. You worry about throwing away spoiled milk, not when you drop off your kids that they're not going to be safe," she said. "There are rules for a reason, and when they are not followed, and things aren't being done the right way, then these horrible things do happen."

The state Division of Children and Families told WISN 12 News reporter Nick Bohr the former Family Tree Learning Center is officially out of business.

The center recently changed hands, though the former owner was still listed with the state as holding the license. Her husband emphasized to WISN 12 News on Monday night that they no longer operated the day care.

"We sold the day care as of the first of the year. This is obviously something legal going on with it. The licensing is still in our name. That was in the agreement," Jeff Berens said.

While the case remains under investigation, the Ozaukee County district attorney told WISN 12 News the only suspect in the reported sexual assaults is the adolescent juvenile.

WISN12 News tried to contact the current day care operator but wasn't able to reach her.
